The veteran third baseman entered play Sunday vs. Seattle batting .341 (15 for 44) with four doubles, one triple and 14 RBI in 12 home games, as opposed to hitting .217 (5 for 23) with one double and one RBI in six road games.
"There are a lot of places to get hits," McGehee said of hitting at home, per MLB.com. "Hitting the ball out of the ballpark is a little more of a challenge here than at some other places. But I feel like I'm strong enough that if I do catch one good, I will be able to drive it out of the ballpark. But I think if you go up with that as your sole goal it's going to make for a long year."
McGehee attributes his strong start to establishing a better approach after he learned to be patient seeing so many forkballs and offspeed pitches playing in Japan last season.
"I think more than anything it was just going and playing every day, and getting back into the mode of being able to have an approach at the plate, and not be so result-oriented all the time, which is easier said than done," McGehee said.
Santana is hitting just .153 through 59 at-bats, and hitting coach Ty Van Burkleo believes he's trying to do too much at the plate. "It just seems like he's trying to do too much," Van Burkleo said. "He went into that spell where he wasn't getting hits, and those 0-fers kind of pile up, and it kind of manifests."
Van Burkleo added that he is trying to get Santana to focus on one at-bat at a time. He praised Santana for his .333 on-base percentage, saying Santana finds a way to contribute even when he's not hitting well.
Petrick, who was the team's minor-league pitcher of the year in 2013, was 2-0 with a 0.48 ERA and 0.75 WHIP in three starts for Double-A Springfield.
"I'm just setting really small goals right now," Hairston said. "We'll complete steps one and two before we see the finish line."
Mastroianni was shipped out in favor of Sam Fuld, who the team claimed on waivers. Mastroianni was hitless in 11 at-bats this season.
"This was full effort for me," he said. "You can't simulate the adrenaline of a big league game. But as far as [a] 10 a.m. sim game, that's all I got."
Kershaw added the soreness and stiffness from the teres major muscle strain in his back that landed him on the disabled list "is gone, and now it's just building back up" arm strength.
